BN Prefix and Three-Letter Location Code
A Brunei Darussalam UN/LOCODE begins with the ISO 3166-1 country prefix BN and is followed by a three-character location identifier, such as BNMUA for Muara.
Brunei Darussalam has 8 ports and terminals indexed in the Ecer Freight database and serves as a strategically positioned maritime gateway for energy, project cargo and regional Southeast Asian trade.
Port coverage includes Muara, Bandar Seri Begawan, the western Belait area and Tanjong Salirong.
Brunei Darussalam has a compact maritime network centered on Muara, with additional listed locations supporting urban, industrial, energy and coastal logistics functions. Ecer Freight indexed coverage is distinct from a national legal count of every landing place or marine facility.
How many seaports does Brunei Darussalam have?
Brunei Darussalam has 8 seaports and terminals indexed by Ecer Freight in its Nov 2026 database snapshot.
What is the largest or busiest port in Brunei Darussalam?
Muara is the principal commercial maritime gateway in Brunei Darussalam and is indexed under UN/LOCODE BNMUA. Muara Harbour, coded BNMUH, is also listed in the local port cluster.
Which area handles the main freight activity?
The Muara area is the main general cargo and container-oriented freight cluster, while Kuala Belait and Seria support western industrial and energy-related logistics. The indexed codes include BNKBT and BNSER.
The table follows the Ecer Freight indexed activity order rather than a global container league table. Publicly comparable 2025 TEU throughput and year-on-year figures were not available for these individual listed facilities, so the ranking, throughput and YoY fields are shown consistently as unavailable rather than estimated.

A Brunei Darussalam UN/LOCODE begins with the ISO 3166-1 country prefix BN and is followed by a three-character location identifier, such as BNMUA for Muara.
Separate codes may identify a city, harbour or operational location. Names that appear similar, such as Muara and Muara Harbour, should therefore be checked against the exact code before booking or preparing shipping documents.
Verify the location against the UNECE UN/LOCODE reference and compare it with the Ecer Freight port directory. Carrier systems and terminal instructions should be checked before final submission.
Brunei Darussalam’s maritime trade is closely connected with Southeast Asian transshipment hubs and energy-related supply chains. Transit times are indicative only and depend on sailing schedules, transshipment, equipment availability, customs clearance and port operations.
A common regional routing for containerized cargo, consolidation, feeder connections and onward global services.
Regional cargo may move through Malaysian gateways for domestic delivery, transshipment and connections to wider Asian networks.
China routings support machinery, consumer goods, industrial inputs and project cargo, often with a regional transshipment leg.
Western industrial locations may support energy-sector supplies, heavy equipment, breakbulk and project movements subject to terminal acceptance.

Official statistical indicators are checked against available government and international references, with page data reviewed quarterly and time-sensitive schedules, capacity and rates subject to confirmation.
